PETA. Ah, Peta. You guys keep getting craftier.

Anyway, you shouldn't believe this video. PETA has been trying to convince everyone to go vegan for years. They've been mashing up videos and making it so that it looks like there's actual cruelty.
Cruelty is fiercly regulated in farms by the government. And I'm not sure if some of that footage was filmed in a different country or if they got their dirty little hands on some old footage, but PETA is a organization of liars. I mean, they get a little too happy with the euthanesia. THAT tells me something.
But I agree. Animal cruelty is a horrible thing.
